HEATER.

Be it known thatL. Fnnnnnicn MAN, a citizen of the United States, residing at Holdenville, in the county of Hughes and State of Oklahoma, have invented. certain new and useful Improvements in Heaters,

of which the following is a specification. c

This invention contemplates an improved heater especially adapted for attachment to an ordinary table lamp although the construction employed is equally applicable for use in connection with various types of ject to provide a constructionhaving the elements thereof so formed and arranged as to produce a maximum result witha given amount of heat from the lamp. 1

Other and incidental objects will appear as the description proceeds and in; the drawferred embodiment of my invention and wherein similar reference-characters designate corresponding parts throughout the several views, I

Figure 1 is avertical se'ctionalyiew showing my improved heater appliedto a lampof conventional form, Fig 2 is a fragmentary perspective view oi the heater, Fig. 3

isaperspective view showing one of the connecting wires detached, the said wires being arranged to join the hood of the heater with the'base thereofand providing handles, Fig. i is an enlargedfrag-me'ntary sectional view particularly showing the dis-w position of the tongues formed from the hood of the device, and Fig.5 isa fragmen tary elevationparticul-a rly showing the contour of the tongues. a

In carrying out my invention-,1 employ a frusto-conical base or body portion 10 which may beformedof sheet metal or other suitable material and which is of a circumfen once at its base to re'movably fit upon the brackets 11 of aconventi ona-l type of lamp shown'a-t 12 in Fig 1 ofthe drawfiI-igs, the

lamp being provided witha suitable burner Specification of Letters Fatent.

detachably supporting a Chimney 13 1 the usualmanner.- 7

The base 10 is ofa length to extend above the mouth of the chimney as shown in Fig. 1 of the drawings and the lower-margin thereof is corrugated circumferentially' as shown at-1,4. Mounted upon the base orl body portion 10 r at the upper extremity thereof is a frusto-conic'al hood 15 which, as 1n the instance of the body portion,- is also" preferably formed of sheet metal althoughas will be clear, any other suitable material may be employed.

The wall of the hood 15 adjacent the lower margin thereof, is corrugated circumof circumferential corrugations .17 are formed in sald hood adjacent the upper ex- .70 ferentially as shown at 16 and a plurality tremity thereof, while the upper margin of the said hood is provided with a series of circumferentially extending and vertically arrangedcorrugations 18.-

'Fitting overthe upper small end of the V hood l5 an annularcapplate 19, the said plate belng of a diameter considerably greater than the diameter of the hood 15 at its smaller'end. and being. provided, adjacent the periphery thereof, with a plurality of circumferential-ly extending corrugations 20; Struckfromthehody of the plate 19,

are a plurality of, tongues 21, the free ex- V V tremit ies of'which are inserted within suitable slots formed in the wall of the hood 1 5;

and then rebent, as best shown inFig. 1 of the drawings for detachably connecting the cap platewiththe hood. It willbe observed that the cap plate 19 forms a' substantial closure for the hood at; its upper end. 7

Struck from the wall of the hood 15 adj acent the lower extremity thereof, is a cir cumferentially spacedseries of vertically ar+ ranged tongues 22, the said tongues being provided with serrated-ledges and being offsetor bent longitudina'llyand inwardly ad- 100 V jacent their upper ends with the free extremities thereof projecting downwardly to ward the" larger end of the hood in spaced relation to the upper smaller extremity of the body portion 10. In thus striking thetongues 22 from the wall of the hood 1'5,a circumferentially spaced series of vertically arranged openings 23 is provided; in the hood adjacent'its lower extremity,,the walls definingsaidopenings also being serrated and in this connection, attention is'called'to the fact that the upper end or mouth of the body portion 10 is disposed in a plane passing through thesaid openings adjacent their upper extremities.

Connecting the hood 15 with the body portion 10, are truss wires 2% arranged at right angles to each other and lnserted within suitable openings formed in the wall of the base 10 adjacent the upper-extremity thereof and in the wall of the hood l5 adjacent its lower extremity. As best shown in Fig. l of the drawings, these wires are arranged. to cross each other at a point axially of the body portion of the hood, the hood being arranged concentric with relation to the body portion with the upper extremity of the body portion projecting a' slight distance'into the hood; As best shown in Fig.

1, the outer extremities of the wires 24 are It will be observed upon references to- Fig. 1 that the wires 24: adjacent the intersection thereof are adapted to rest upon the upper end of the chimney 13 to thus coact with the body portion 10 in supporting the heater upon the lamp. In use, heat rising from the burner .through'the chimney 13 will be discharged at the mouth of t is chimney to enter'within the hood 15. The heat being so dischar ed from the chimney will create a fresh air draft through the body portion IO'Wl'llCh draft, upon-coming 1n contact with the heat issuing from the chimney, will tend to intensify the heated currents within the-hood. These heated. currents will then rise within the hood to come in contact with the corrugations 17 and 18 andf thus becomethoroughly mingled.

As will be clear, currents rising within the hood 515 will be deflected by the cap plate 19 downwardly within the hood to strike the tongues 22 which, as will be seen, thus pro- .v1de a series of radially extend1ng=baifie plates tending to further mingle the fresh air draftswith the heat rising from the chimney. The serrated edges of the tongues 22 as well as the serrated walls definingthe openings 23 will, as the said currents flow over the tongues and through the openings,

materially assist in thoroughly mixingthe heated and fresh air currents issuing from the hood. Theheated currents upon lssuing through the openings 23 will immediately ascend to strike the outer corrugated margin of the cap plate 19 which action as I will be understood, will tend to. diffuse the,

place where i the-body portion, the said hood being proheat withinv the room or other the heater is used.

i It "will therefore be seen that I providela very simple and eflicient construction for the.

purpose set forth and while I have illus trated a'heater especially adapted for at taehnient to an ordinary'table lamp, still;

burners, this modification in construction be" ing entn'elywithin ti'lBiSPlI'lt of the. present invention as" defined in the claims appended hereto;

As shownin Fig. i of the drawings, the; free ends of th'e'tongues22 are bent inwardly toward the body portion 10' at a relatively sharpangle and may, if desired,-

be arranged to contact with the upper ex tremity of the said body portion atftheiri outer terminals, to thus center the hood upon the body portion. Preferably the tongues 22 are laterally enlarged adjacent the outer extremities thereof as more par= t1cularlyshown 1n Figwo of the drawings, so that the transverse width of each of the openings formed in thehood is greater at the lower ends of the said openings than at the upper ends thereof.

)onsequently, heat passing downwardlywithin the hood 15 as previously described and upon comingin contactwith the tongues 22,*w1ll tend to create a suction within the upper restricted area of the said openings and consequently maintain a free circulation of heated cur;-

rents. through the body portion 10- and {is through the hood. The tongues are preferably arranged to intersect the plane of the top of the body portion 10, or, in. other words, are arranged to surround the open end the said body portion so that" the downwardly movingair currents within the hood will be delayed immediately at the point where the heated air currents issue from the body portion and will thus, while 1 the heated air currents are at their maximum temperature, be intimately sub ecteclv to the influence thereof a relatively long time, to thus become the more intensely-- heated. The reason forearranging the open:

ings 23 to intersect the open endof the plane of the body portion 10 will also now be clear since it will be seen that the said heated currents flowing downwardly within the hood 16, Wlll be permitted to escape from the hood only after the said icurrents have been heated to a maximum temperature.
